摘要
证明了有限时滞系统解的毕竟有界性蕴含周期解的存在性 。
It has been proved that wltimate bound-ness of solutions implies the existence of periodic solution to the functional differential equation with finite delay,so the ruslt of ordinary differential equation has been extented to functiond differential equation with finite delay.
